Disclosed is an indoor unit for an air conditioner. The indoor unit for the air conditioner according to the present invention includes: a cabinet assembly forming an external appearance of the indoor unit and having an air suction port formed in a rear of the cabinet assembly; a filter module disposed at the air suction port to filter dust contained in air being introduced through the air suction port; a filter cleaner configured to move upward and downward in a rear of the filter module to remove foreign substances stuck in the filter module; a guide rail vertically disposed on one side of the filter module and configured to guide upward and downward movement of the filter cleaner, wherein the filter cleaner comprises: a mobile gear configured to rotate while engaged with the guide rail to move the filter cleaner upward and downward with respect to the filter module, a gear motor configured to rotate the mobile gear, an agitator configured to rotate in friction with the filter module, a dust container disposed downward of the agitator and collecting foreign substances separated from the filter module due to the rotation of the agitator, and a guide roller bringing the filter cleaner into close contact with the filter module so that part of the agitator rotates while in contact with the filter module.

An air cleaner is provided that may include at least one blowing device including a main fan that generates air flow and a first discharge outlet through which air passing through the main fan is discharged; a flow controller movably provided at one side of the at least one blowing device, the flow controller including a sub-fan that generates air flow and a discharge grill through which air passing through the sub-fan is discharged; and a display provided in the discharge grill, the display device displaying operation information.

A filtration unit (1) comprising a support (10) arranged to receive a plurality of filter cartridges (11,11), the support configured to allow a displacement of the cartridges between a working position (70), in which a first filter cartridge (11) is arranged with own inlet/outlet apertures (71,71) in communication with a fluid inlet and outlet line portions (7,8), respectively, and at least one standby position (75) configured for receiving a respective second filter cartridge (11), an exchange mechanism (12) configured for causing the displacement of the cartridges between the at least one standby position and the working position, a differential pressure sensor (80) configured for measuring a pressure drop through first filter cartridge arranged in the working position and for generating a differential pressure signal (286) responsive to the pressure drop, a control unit (90) configured for receiving the differential pressure signal (86) and for providing an actuation signal (287) of the exchange mechanism, a program means resident in the control unit (90) and configured for generating the actuation signal (287) when the differential pressure signal indicates a pressure drop value exceeding a predetermined lower threshold value. This way, it is possible to arrange a clean filter cartridge in the at least one standby position, ready to be displaced to the working position in replacement of first filter cartridge, and the at least one second clean filter cartridge is transferred to the working position upon exceeding the differential pressure threshold value, remarkably limiting filter maintenance time and costs in a complex fluid distribution network.

An air cleaner is provided that may include a first air cleaning module having a first fan that generates air flow from a first suction inlet toward a first discharge outlet; a second air cleaning module having a second fan that generates air flow from a second suction inlet toward a second discharge outlet; a dividing plate provided between the first air cleaning module and the second air cleaning module; and a display provided at inside of the dividing plate and in which a light source is provided.

Disclosed is an indoor unit for an air conditioner.
